EASA Part 145 Audit Questions

  • EASA 145.A.10 - Scope

  • This Section establishes the requirements to be met by an organisation to qualify for the <br>issue or continuation of an approval for the maintenance of aircraft and components.<br><br>1. Line Maintenance should be understood as any maintenance that is carried out before flight to ensure that the aircraft is fit for the intended flight.<br>(a) Line Maintenance may include:<br>- Trouble shooting.<br>- Defect rectification.<br>- Component replacement with use of external test equipment if required. <br>Component replacement may include components such as engines and pro-<br>pellers.<br>- Scheduled maintenance and/or checks including visual inspections that will <br>detect obvious unsatisfactory conditions/discrepancies but do not require <br>extensive in depth inspection. It may also include internal structure, systems <br>and powerplant items which are visible through quick opening access panels/<br>doors. <br>- Minor repairs and modifications which do not require extensive disassembly and can be accomplished by simple means.<br>(b) For temporary or occasional cases (AD’s, SB’s) the Quality Manager may accept base maintenance tasks to be performed by a line maintenance organisation provided all requirements are fulfilled as defined by the competent authority.<br>(c) Maintenance tasks falling outside these criteria are considered to be Base Maintenance.<br>(d) Aircraft maintained in accordance with ‘progressive’ type programmes should be individually assessed in relation to this paragraph. In principle, the decision to allow some ‘progressive’ checks to be carried out should be determined by the assessment that all tasks within the particular check can be carried out safely to the required standards at the designated line maintenance station.<br>2. Where the organisation uses facilities both inside and outside the Member State such as satellite facilities, sub-contractors, line stations etc., such facilities may be included in the approval without being identified on the approval certificate subject to the maintenance organisation exposition identifying the facilities and containing procedures to control such facilities and the competent authority being satisfied that they form an integral part of the approved maintenance organisation.

  • EASA 145.A.15 - Application

  • An application for the issue or change of an approval shall be made to the competent authority in a form and manner established by such authority.<br><br>In a form and in a manner established by the competent authority means that the application should be made on an EASA Form 2 (refer to Appendix III to AMC to Part-145).

  • EASA 145.A.20 - Terms of Approval

  • The organisation shall specify the scope of work deemed to constitute approval in its exposition (Appendix IV to Annex I (Part-M) contains a table of all classes and ratings).

  • EASA 145.A.25 - Facility Requirements

    The organisation shall ensure that:

  • (a) Facilities are provided appropriate for all planned work, ensuring in particular, protection from the weather elements. Specialised workshops and bays are segre- gated as appropriate, to ensure that environmental and work area contamination is unlikely to occur. 1. For base maintenance of aircraft, aircraft hangars are both available and large enough to accommodate aircraft on planned base maintenance; 2. For component maintenance, component workshops are large enough to accom- modate the components on planned maintenance.

  • (b) Office accommodation is provided for the management of the planned work referred to in paragraph (a), and certifying staff so that they can carry out their designated tasks in a manner that contributes to good aircraft maintenance standards.

  • (c) The working environment including aircraft hangars, component workshops and office accommodation is appropriate for the task carried out and in particular special requirements observed. Unless otherwise dictated by the particular task environment, the working environment must be such that the effectiveness of personnel is not impaired:<br>1. temperatures must be maintained such that personnel can carry out required tasks without undue discomfort.<br>2. dust and any other airborne contamination are kept to a minimum and not be permitted to reach a level in the work task area where visible aircraft/component surface contamination is evident. Where dust/other airborne contamination results in visible surface contamination, all susceptible systems are sealed until <br>acceptable conditions are re-established.<br>3. lighting is such as to ensure each inspection and maintenance task can be carried out in an effective manner.<br>4. noise shall not distract personnel from carrying out inspection tasks. Where it is impractical to control the noise source, such personnel are provided with the necessary personal equipment to stop excessive noise causing distraction during inspection tasks.<br>5. where a particular maintenance task requires the application of specific environmental conditions different to the foregoing, then such conditions are observed. Specific conditions are identified in the maintenance data.<br>6. the working environment for line maintenance is such that the particular maintenance or inspection task can be carried out without undue distraction. Therefore where the working environment deteriorates to an unacceptable level in respect of temperature, moisture, hail, ice, snow, wind, light, dust/other airborne contamination, the particular maintenance or inspection tasks must be suspended <br>until satisfactory conditions are re-established.<br>

  • (d) Secure storage facilities are provided for components, equipment, tools and material. Storage conditions ensure segregation of serviceable components and material from unserviceable aircraft components, material, equipment and tools. The conditions of storage are in accordance with the manufacturer’s instructions to prevent deterioration and damage of stored items. Access to storage facilities is restricted to authorised personnel.

  • EASA 145.A.30 - Personnel Requirements

The appointed person shall have direct access to the accountable manager to ensure that the accountable manager is kept properly informed on quality and compliance matters.<br>

  • (d) The organisation shall have a maintenance man-hour plan showing that the organisation has sufficient staff to plan, perform, supervise, inspect and quality monitor the organisation in accordance with the approval. In addition the organisation shall have a procedure to reassess work intended to be carried out when actual staff availability is less than the planned staffing level for any particular work shift or period.<br>

  • (e) The organisation shall establish and control the competence of personnel involved in any maintenance, management and/or quality audits in accordance with a procedure and to a standard agreed by the competent authority. In addition to the necessary expertise related to the job function, competence must include an understanding of the application of human factors and human performance issues appropriate to that person’s function in the organisation. “Human factors” means principles which apply to aeronautical design, certification, training, operations and maintenance and which seek safe interface between the human and other system components by proper consideration of human performance. “Human performance” means human capabilities and limitations which have an impact on the safety and efficiency of aeronautical operations.

  • (f) The organisation shall ensure that personnel who carry out and/or control a continued airworthiness non-destructive test of aircraft structures and/or components are appropriately qualified for the particular non-destructive test in accordance with the European or equivalent Standard recognised by the Agency. Personnel who carry out any other specialised task shall be appropriately qualified in accordance with officially recognised Standards. By derogation to this paragraph those personnel specified in paragraphs (g) and (h)(1) and (h)(2), qualified in Part-66 category B1 may carry out and/or control colour contrast dye penetrant tests.

  • (g) Any organisation maintaining aircraft, except where stated otherwise in paragraph (j), shall in the case of aircraft line maintenance, have appropriate aircraft type rated certifying staff qualified as category B1 and B2 in accordance with Part-66 and 145.A.35.In addition such organisations may also use appropriately task trained certifying staff qualified as category A in accordance with Part-66 and 145.A.35 to carry out minor scheduled line maintenance and simple defect rectification. The availability of such category A certifying staff shall not replace the need for Part-66 category B1 and B2 certifying staff to support the category A certifying staff. However, such Part-66 category B1 and B2 staff need not always be present at the line station during minor scheduled line maintenance or simple defect rectification.

  • (h) Any organisation maintaining aircraft, except where stated otherwise in paragraph (j) shall:<br>1. in the case of base maintenance of large aircraft, have appropriate aircraft type rated certifying staff qualified as category C in accordance with Part-66 and 145.A.35. In addition the organisation shall have sufficient aircraft type rated staff qualified as category B1 and B2 in accordance with Part-66 and 145.A.35 to support the category C certifying staff.<br>(i) B1 and B2 support staff shall ensure that all relevant tasks or inspections have been carried out to the required standard before the category C certifying staff issues the certificate of release to service.<br>(ii) The organisation shall maintain a register of any such B1 and B2 support staff.<br>(iii) The category C certifying staff shall ensure that compliance with paragraph <br>(i) has been met and that all work required by the customer has been accomplished during the particular base maintenance check or work package, and shall also assess the impact of any work not carried out with a view to either requiring its accomplishment or agreeing with the operator to defer such <br>work to another specified check or time limit.<br>2. in the case of base maintenance of aircraft other than large aircraft have either:<br>(i) appropriate aircraft type rated certifying staff qualified as category B1 and B2 in accordance with Part-66 and 145.A.35 or,<br>(ii) appropriate aircraft type rated certifying staff qualified in category C assisted by B1 and B2 support staff as specified in paragraph (1).<br>

  • (i) Component certifying staff shall comply with Part-66.

  • (j) By derogation to paragraphs (g) and (h), the organisation may use certifying staff qualified in accordance with the following provisions:<br>1. For organisation facilities located outside the Community territory certifying staff may be qualified in accordance with the national aviation regulations of the State in which the organisation facility is registered subject to the conditions specified in Appendix IV to this Part.<br>2. For line maintenance carried out at a line station of an organisation which is located outside the Community territory, the certifying staff may be qualified in accordance with the national aviation regulations of the State in which the line station is based, subject to the conditions specified in Appendix IV to this Part.<br>3. For a repetitive pre-flight airworthiness directive which specifically states that the flight crew may carry out such airworthiness directive, the organisation may issue a limited certification authorisation to the aircraft commander and/or the flight engineer on the basis of the flight crew licence held. However, the organisation shall ensure that sufficient practical training has been carried out to ensure that such aircraft commander or flight engineer can accomplish the airworthiness directive to the required standard.<br>4. In the case of aircraft operating away from a supported location the organisation may issue a limited certification authorisation to the commander and/or the flight engineer on the basis of the flight crew licence held subject to being satisfied that sufficient practical training has been carried out to ensure that the commander or flight engineer can accomplish the specified task to the required <br>standard. The provisions of this paragraph shall be detailed in an exposition procedure.<br>5. In the following unforeseen cases, where an aircraft is grounded at a location other than the main base where no appropriate certifying staff are available, the organisation contracted to provide maintenance support may issue a one-off certification authorisation:<br>(i) to one of its employees holding equivalent type authorisations on aircraft of similar technology, construction and systems; or<br>(ii) to any person with not less than five years maintenance experience and holding a valid ICAO aircraft maintenance licence rated for the aircraft type requiring certification provided there is no organisation appropriately approved under this Part at that location and the contracted organisation obtains and holds on file evidence of the experience and the licence of that <br>person. All such cases as specified in this subparagraph shall be reported to the competent authority within seven days of the issuance of such certification authorisation. The organisation issuing the one-off authorisation shall ensure that any such maintenance that could affect flight safety is re-checked by an appropriately approved organisation.
